SFC is really sfc.exe. Sfc.exe is Windows 2000 System File Checker.

To show what is happening while sfc /scannow is running...

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
Value Name: SFCShowProgress
Data Type: REG_DWORD
Value Data: (0 = disabled, 1 = enabled)

If you do not have the key shown above, create it and set the Value Data to
1.

Instructions here >>>
Display SFC Progress Meter

The key you're referring to is this >>>
And Sfc sets the value data:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
Value Name: SFCScan
Data Type: REG_DWORD
Value Data: 0
